  • Patent number: 8850836
    Abstract: A temperature regulation system for air inside of a vehicle regardless of the on/off state of the vehicle's ignition or engine includes a rechargeable battery for supplying power to an air moving system and a heat exchanger in accordance with demand signals from a thermostat. A motor-generator has a motor mode wherein electrical energy from the battery is converted into rotational kinetic energy and coupled to an AC compressor, and a generator mode wherein rotational kinetic energy from the engine is converted into electrical energy to recharge the battery. A control circuit is electrically connected with the motor-generator and adapted to activate the motor mode when the engine is off and the air temperature inside the vehicle exceeds the desired temperature range, the motor-generator otherwise being in the generator mode. Alternate embodiments includes a motor-compressor that replaces the stock compressor of the vehicle.

  • Patent number: 8826681
    Abstract: An air conditioner for vehicles in which the probability of executing pre-air conditioning is increased so that it may be prevented that the inside of the vehicle cannot be often in a comfortable state before the driver gets into the vehicle. The air conditioner performs air conditioning of a vehicle having a traveling motor and an engine as drive sources and comprises a pre-air conditioning main switch. The crew permits operation of pre-air conditioning by turning the switch on. When the pre-air conditioning main switch is set on, an engine control section performs charge preference control where battery charge takes precedence of engine fuel consumption and performs normal control where engine fuel consumption takes precedence when the pre-air conditioning main switch is set off.

  • Patent number: 8806880
    Abstract: An expansion valve for reducing the quantity of material required for the valve body by contriving the arrangement of bolt fitting grooves. In the expansion valve (20), displacement of a valve member driver (36) provided in the valve body (21) is transmitted to a valve member by a valve member drive rod (36f) and the valve opening is altered to control the flow rate of the refrigerant. The valve body (21) consists of a body upper portion (40) and a body lower portion (41) narrower than the body upper portion (40), and bolt fitting grooves (43, 43) opening in the flank of the valve body (21), preferably opening obliquely downward, are formed at the boundary (42) of the body upper portion (40) and the body lower portion (41). With such a layout, the material required at the boundary (42) can be reduced furthermore and the quantity of material required for the valve body (21) can be reduced furthermore, as a result.

  • Patent number: 8756948
    Abstract: A system for conditioning air in a structure includes a first conditioning system and a second conditioning system. The first conditioning system is capable of supplying conditioned air to a first space of the structure. The first space is enclosed, at least in part, by one or more external walls. The second conditioning system is capable of supplying conditioned air to a second space of the structure that is located above the first space. The second space is enclosed, at least in part, by a roof that is sealed to prevent a flow of air between the second space and an outside environment. The first space and the second space are separated by a ceiling that permits thermal energy to pass between the first space and the second space.

  • Patent number: 8667806
    Abstract: A heat pump liquid heater (HPLH) system coupled to an array of photovoltaic cells that operate at enhanced efficiency is disclosed. The HPLH system comprises a panel or a box structure coupled to the HPLH. The box structure supports an array of photovoltaic cells and a circulation mechanism. The HPLH generates a coolant as a by-product using ambient air and electric power. The coolant that is circulated around the photovoltaic cells may extract the heat generated by the photovoltaic cells and the temperature of the photovoltaic cells may decrease to a specific level or maintained within an allowable temperature range. The reduction in temperature causes the photovoltaic cells to operate with enhanced efficiency and may generate more electric power. The size of the panel or the number of photovoltaic cells required to generate a required power may be reduced that reduces the cost of the HPLH system.
